If there is an unconditioned plenum/attic above the space then heat gain into the space will be through internal surface conduction (ceiling of the space into the floor of the attic/plenum).

That appears to also be zero for this space however....you might need to elaborate on how this space is configured as far as how the roof is connected or not connected to the space.

eQUEST doesn't directly report a ventilation load, the reports are only for loads placed on AHU coils. There are some messages in the archive that discuss different approaches to quantifying that number.

Energy-Models.com is a site for energy modelers, building simulators, architects, and engineers who want learn the basics, to advanced concepts of energy modeling. We've got online training courses and tutorials for eQUEST, Trane TRACE 700, OpenStudio, and LEED for energy modeling. All our energy modeling courses are video based. What better way to learn energy modeling software than screen-casts of exactly how things are done?
